A runner exerts a force of 234 N against the ground while using 1100 W of power.How long does it take them to run a distance of 30.0 m
1 answer:
<h3>
Answer: </h3>
6.38 seconds
<h3>
Explanation: </h3>
We are given;
The force exerted by the runner as 234 N Power used = 1100 W Distance as 30.0 m We are required to determine the time taken to run the distance;
We know that power is the rate of work done That is;
Power = work done ÷ time
But, work done = Force × distance
Therefore;
Work done = 234 N × 30 m
= 7020 Joules
Therefore, from the formula, Power = work done ÷ time
Time = Work done ÷ power
Thus;
Time = 7020 J ÷ 1100 W
= 6.38 seconds
Hence, the time taken is 6.38 seconds
